MACHINE FOR MAKING BRICKS.

Specification of Letters Patent No. 601, dated February 15, 1838.

T0 all whom t may concer-n.'

Be it known that I, JESSE REEDER, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Machines for Making Bricks, which is described as follows,v referencebeing had to the annexed drawings of the same, making part of thisspecification.

First. Construct a permanent circular stone or wooden foundation A,Figure 7 40 feet in diameter (more or less) rising to the surface of theground to support a plat form B. Then a po-st C Figs. l and 3 of about18 inches diameter is to be planted in the center of the circle rising14 feet high. Then 8 pieces D Fig. l 8 inches square are framed into thecenter post radiating to the outer edge of the wall and resting upon thefoundation. Then braces E Fig. l of the same size framed into each space7 feet from the o-uter end to receive 7 joists F, in each space 6 by 8inches. Then a iioor of oak or beech plank 2 feet wide 2 thicknesses of4 inch stuff, broke joints, spiked down to the joists to support themolds in which the brick are made by a revolving wheel of about 8 tonsweight.

2nd. The molds I are made of metal 4 (more or less) in a flight castwhole or in separate parts see Figs. l, 4, 5 and 6 so that they may beground smo-oth ywith a tenent on the dividing pieces to go through theside pieces and fastened by a draw pin-a groove the of an inch deepextending from the mortise each way to the edge of the side pieces toreceive the shoulders of the tenented bar of .l inch thick and 2% inchesdeep: the dividing bars would be more durable if made of wrought iron.The side pieces cast same depth inch thick at the top edge and l inch atthe bottom with mortises to receive the tenents of cross bars andflanges on each side with a. holein each to receive a spike to fasten itdown. Although I have here described a mold constructed in separateparts yet I prefer the one cast whole. The followers K Fig. 7 are castof an inch thick fitting the inside of the molds with an inch and a isocket and 15; inch deep to receive a pin L 'pressing through the floor-to a treadle M which, by stepping upon it, will raise the brick. Themolds are to be set to a circle drawn on the platform 4 inches from theperiphery leav- Ing a suitable space between each flight.

3rd. The wheel N Fig. l before mentioned, isv to be made of timber orother material from 8 to l0` feet diameter with a shaft O through thecenter fastened to the center post by 2 semicircular bands P and aswivel bolt Q, passing through it into the end of the shaft. The wheelto be of about 3 tons weight propelled by a horse or lby oxen hitched tothe shaft inside the wheel and molds. The molds are lilled with clay asdug from the bank and 3 or 4 revolutions of the wheel passing over themwillV form the brick.

4th. As a substitute for the wheel a wooden or metal hammer a Fig. 11maybe used weighing about 600 pounds with a shaft b extending to thecenter post and fastened by a khinged band around it and bolted l to thesides of the shaft, having a cast roller o Figs. l and 2 near the hammeron the under edge of the shaft to slide up an inclined scantling risingabout one' foot from the center of one mold to the center of another andthen suddenly falling olf the end upon the clay on the molds and thuspounding it into a solid mass.

The invention claimed by me the said JEssE REEDER and which I desire tosecure by Letters Patent consists in- The combination of the circle ofmolds and their appendages with the wheel N for Y Y WM. l?. ELLIOT,
